Question

If a 45-gal hot water tank holds 375 lb of water, what weight of water will a 55-gal tank hold? (Round to the nearest pound.)

Answer 1

Given:

A 45-gal hot water tank holds 375 lb of water.

`\begin{gathered} 45\text{ gal }\rightarrow375\text{ lb} \\ 55\text{ gal}\rightarrow x?\text{ lb} \end{gathered}`

To find the values of x,

`\begin{gathered} (45)/(375)=(55)/(x) \\ 45x=55\cdot375 \\ 45x=20625 \\ x=458.33\text{ lb} \end{gathered}`

Answer: The weight of water which will hold 55 gal tank is 458 lb.
